ALBERT SCHEIBLE, OF CHICAGO, ILLINOIS.

SPRING.

To all whom it may concern:

Be it known that I, ALBERT SCHEIBLE, a citizen of the United States, andresiding at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Spring, of which the following is a clear,concise, and full specification, reference be ing had to theaccompanying drawings, forming part of this application.

My invention relates to springs, being particularly applicable tocompression springs as used on spring beds. Its object is to provide aneasily made spring which will permit of being greatly compressed withoutputting a severe torsional strain on the material of which it is made,and which will be more resilient than the spirally coiled springs incommon use. I attain these objects. by the construction shown in theaccompanying drawings, in which- Figure 1 is a side elevation of thepreferred form of my invention. Fig. 2 is a top View of the same. Fig. 3is a perspective of an alternative form having the fastening wings orterminal loops in the same planes wit-h the return bends. Fig. l showsanother shape of terminal wing.

Referring to the drawings, the spring of my invention is made with acentral portion A connecting coils B and C which are coiled in oppositedirections and which preferably lie in parallel planes. At each end ofthe spring I provide an attaching loop or wing, preferably in the formof an elongated loop. If the spring is to be interposed between parallelsurfaces, as between a slat and a bedbottoin, the terminal wings D and Dlie in horizontal planes substantially parallel to the central portion Aand substantially at right angles to the planes of the vertical coils Band G. However, if the ends of the spring are to be fastened to membersin a common plane, the wings are turned in substantially the same planewith the coils B and C, as in Figs. 3 and 4. In either case, I interposea U- shaped portion or return bend between the coil and the wingadjacent to it, as shown at E and F.

The attaching wings D and D preferably have their centers on a line G Gpassing through, the middle of the central part A at right angles to thelatter, so that these wings will move to and fro along this line whenthe spring is compressed or distended. In using such a spring, theterminal loops Specification of Letters Patent.

have found that when such a direct connec-.

tion is made from the coil of a spring to its terminal fastening, thepower required to flex or twist the juncture of the spring with theterminal interferes greatly with the resiliency of the spring. However,if a return bend is introduced between the coil and the terminal, thisbend will open or close more or less when the spring is compressed ordistended, thereby enabling me to utilize the full resiliency of eachcoil.

\Vhile I preferably make my spring with the central portion A parallelto the legs J K of the return bends at each end, I do not wish to belimited to this parallel position of the members when the spring isdistended, since the central member may be at an angle to the legs ofthe return bends, as in Fig. 3. Neither do I wish to be limited to theexact shape or arrangement of the terminals or attaching wings used withthe spring of my invention, as numerous modifications may be made in thesame without departing from the spirit of my invention.

hat I claim as new and desire to coverby Letters Patent is:

1. A spring composed of a single strand of wire having a substantiallyhorizontal and substantially straight central portion, each end of thecentral portion being developed into a vertical coil; and an attachingWing at each end of the spring; there being a return bend interposedbetween each attaching wing and the adjacent vertical coil.

2. A spring composed of a single strand of wire terminating in upper andlower attaching wings, including a pair of vertical coils joined by asubstantially straight central portion; and U-shapedportions-intermediate of the coils and the attaching wings, the legs ofthe U-shaped portions being substantially horizontal.

3. spring composed of a single strandtions intermediate of the coils andthe acljal attaching Wing and the adjacent vertical cent attachingWings.

4. A spring composed of a single strand of Wire terminating in upper andlower attaching wings, including a pair of coils in substantiallyparallel Vertical planes; there being a return bencl interposed betweeneach coil, the return bends being in substantially vertical planes.
